A/C Evaporators and Parts

The evaporator essentially works the same way as a condenser, except in reverse. The idea is that once the pressurized refrigerant has been condensed into a liquid, then depressurized and cooled by the expansion valve, it enters the evaporator, which due to its construction allows the temperature of the coils inside to drop considerably. Usually, then a fan blows air over the evaporator. The oncoming air is cooled by the evaporator, then sent out the vents of the dashboard, and right onto your face.

A/C Receiver Driers

The receiver dryer is placed in the air conditioning system in order to collect any moisture in the system. Over time, the receiver dryer can lose its effectiveness, causing excess moisture to build up in your A/C system. It is also highly recommended that the receiver dryer be replaced any time the A/C system is opened up to outside air.
